Vein deposits of dolomite occur with quartz and other common vein minerals, such as calcite, magnesite, fluorite, siderite, and sphalerite, or with metallic ore minerals such as galena, pyrite and chalcopyrite. Although uncommon, when dolomite occurs in altered ultramafic igneous rocks, it may be associated with magnesite, serpentine, and talc.

Calcite - Mineral, Crystals, Sedimentary Rocks: A large percentage of the calcite in rocks was deposited in sedimentary environments; consequently, calcite is a constituent of several diverse sediments, sedimentary rocks, and their metamorphosed products. A minor amount of the Earth's calcite is of magmatic (i.e., igneous) origin; it is …

Calcite photo provided by Collector's Edge Minerals – @collectorsedgeminerals. The crystal calcite can be found all over Minnesota. It's mostly composed of calcium carbonate, which is also found in eggshells and chalk. There are many calcite shades, from clear and white to pink and even blue.
calcite, the most common form of natural calcium carbonate (CaCO 3), a widely distributed mineral known for the beautiful development and great variety of its crystals. It is polymorphous (same chemical formula but different crystal structure) with the minerals aragonite and vaterite and with several forms that apparently exist only under …
Since it forms primarily from evaporation, halite normally is found with other evaporation-associated minerals such as calcite, gypsum, anhydrite, and sylvite. Sylvite, although rare, is poisonous - so it is a good idea to use your finger to test an unknown sample's taste, rather than directly licking the sample.
Manganoan calcite provided by Spirifer Minerals. Manganoan calcite is a special kind of calcite that gets its pink color from manganese in its structure. The more manganese it has, the pinker it looks, which makes it really stand out among other minerals. This type of calcite often forms in well-shaped crystals that can be …

This photo shows a bunch of calcite cleavage fragments. Compare the shape of these fragments with the clear calcite shown in Figure 3.38. Besides calcite, dolomite and other carbonate minerals that belong to the rhombohedral carbonate group, cleave the same way. Some carbonates, such as aragonite and cerussite, however, are …
Calcite is the principal constituent of limestone and marble. These rocks are extremely common and make up a significant portion of Earth's crust. They serve as one of the largest carbon repositories on our planet. The properties of calcite make it one of the most widely used minerals.
